Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of an application of a method for resetting an OLT optical module provided in an embodiment of the present application, where the scenario includes a GPON system, and the GPON system includes an OLT (Optical Line Terminal ) and n ONUs (Optical Network Unit, optical network units), where the OLT is a device connected to an optical fiber trunk, the ONUs are user-side devices, and the OLT and the ONUs are connected to each other by an ODN (Optical Distribution Network, passive optical network) to perform communication. In the upstream direction, in order to prevent collision between ONUs, each ONU can transmit upstream data (optical signal) to the OLT only in a time slot in which the ONU is allowed to transmit itself by a time division multiplexing method. After the OLT receives and processes the optical signal, it outputs an electrical signal to a BCDR (Burst mode Clock and Data Recovery, burst mode clock data recovery) module, and then the BCDR module performs data recovery.
Ideally, an idle period without light exists between the effective optical signal sent by the previous ONU and the effective optical signal sent by the next ONU, and the OLT optical module output is 0 or is steady in the idle period. However, in an actual scene, the optical signals have noise interference and other conditions in an idle period, the noise is input into the OLT optical module, so that an output electrical signal of the OLT optical module is in an unstable state, and when the electrical signal in the unstable state is input into the BCDR module, the locking time of the BCDR module on a channel after the next effective electrical signal is longer, and the data recovery cannot be completed within a specified time.
Based on the above, the application provides a resetting method of an OLT optical module, which is used for relieving the technical problem that the locking time of the current BCDR module is longer.
Referring to fig. 2, fig. 2 is a flowchart of a method for resetting an OLT optical module according to an embodiment of the present application, where the method specifically includes:
s1: and acquiring a first end time of the target ONU for transmitting the effective optical signal to the OLT optical module.
The target GPON may be any ONU in the GPON system that can perform normal communication with the OLT optical module, where the target ONU sends an effective optical signal to the OLT in its own timeslot, and the end time of sending the effective optical signal is the first end time.
In one embodiment, S1 specifically includes:
s11: and acquiring a second ending time of the OLT optical module for processing the effective optical signal to obtain the effective electrical signal.
S12: and acquiring the processing time delay of the OLT optical module on the effective optical signal.
S13: and obtaining the first ending time according to the difference value of the second ending time and the processing time delay.
Before the target ONU sends a valid optical signal to the OLT optical module, the OLT optical module sends an Upstream BWmap data item to the target ONU through a downstream frame. As shown in fig. 3, the structure of the data item includes a PCBd field (frame header) and a GTC payload field (payload), where the PCBd field includes a Psync field, an event field, a PLOAMd field, a BIP field, a Plend field, an Upstream Bwmap field, and the Upstream Bwmap field includes an Alloc-ID field, a Flags field, a StartTime field, a StopTime field, and a CRC field.
The effective optical signal is converted into an electrical signal, converted into a parallel electrical signal by a serial electrical signal, converted into a parallel electrical signal by a clock domain, and the like in the OLT optical module, and finally the effective electrical signal is output. The StartTime in the StartTime domain refers to the starting time of the transmission of the effective electrical signal in the OLT-side transmission convergence layer, that is, the time when the effective optical signal starts to obtain the effective electrical signal after the series of processes, and the StopTime in the StopTime domain is the ending time of the transmission of the target electrical signal in the OLT-side transmission convergence layer, that is, the time when all the effective optical signals have completed the processes and obtained the effective electrical signal. In the embodiment of the present application, stopTime is referred to as the second end time of the effective electrical signal.
The first end time of the effective optical signal cannot be directly obtained but needs to be calculated, and in this embodiment, the first end time is equal to the difference StopTime-T1 between the second end time StopTime of the effective electrical signal and the processing delay T1 of the effective optical signal. The processing delay T1 of the OLT optical module mainly comprises the following three parts: firstly, the time Ta of the photoelectric conversion of an OLT optical module; secondly, the time Tb for converting the serial electric signal into the parallel electric signal; finally, the time Tc of the clock domain conversion of the parallel electric signals; i.e. t1=ta+tb+tc.
When the OLT optical module sends the Upstream BWmap data item to the target ONU through the downstream frame, a part of the Upstream BWmap data item is locally stored, so that the second end time StopTime can be directly obtained from the local when needed, and for each determined OLT optical module, the processing delay T1 can be obtained by directly reading the factory configuration or performing experiments. After the two data are obtained, the first end time of the effective optical signal can be accurately calculated, so that the reset starting time can be accurately determined later.
In one embodiment, before S1, further comprising:
s1a: the first starting time of the target ONU for transmitting the effective optical signal to the OLT optical module is obtained.
S1b: and determining a first front reset starting moment corresponding to the effective optical signal according to the first starting moment.
S1c: and generating a first front reset signal at the first front reset starting moment, and carrying out front reset on the OLT optical module through the first front reset signal.
The target ONU transmits an effective optical signal to the OLT in a time slot of the target ONU, and the starting time of transmitting the effective optical signal is a first starting time. In order to correctly restore the original data of the ONUs, the OLT optical module needs to adjust a receiving level decision threshold according to the optical signals of the ONUs, however, because the distances of different ONUs reaching the OLT are not equal and the intensities of the optical signals sent by the optical modules of each ONU are different, the signal power received by the receiver of the OLT is not the same in each time slot, which is easy to cause the optical module of the OLT to generate erroneous decision. To solve this technical problem, a pre-reset mechanism may be adopted, specifically: the first starting moment is determined as a first front reset starting moment corresponding to the effective optical signal, a front reset signal is generated in a reset circuit at the first front reset starting moment and is input into the OLT optical module through a corresponding interface in the OLT optical module, the front reset is carried out on the OLT optical module, the gain coefficient and the bandwidth of the OLT optical module are restored to default values, the front reset lasts for a period of tens of nanoseconds, and after the front reset signal is released, the OLT optical module adjusts a receiving level judgment threshold according to the currently received effective optical signal.
As shown in fig. 4, ONU1 and ONU2 respectively transmit effective optical signals in respective time slots, taking the effective optical signal transmitted by ONU1 as an example, since the effective optical signal is unstable to a stable state (the waveform in the figure has undulation), the direct judgment is easy to cause erroneous judgment, and after adopting the pre-reset mechanism, the unstable part of the optical signal in the effective optical signal can be reset, so that the unstable part of the optical signal does not enter the BCDR module, and only the stable part of the optical signal enters the BCDR module after being processed, the erroneous judgment is not easy to generate.
Although the mode of resetting before the initial position of the optical signal can solve the technical problem of misjudgment, when the differential signal output by the OLT optical module is in an unstable state after the signal is ended, the locking time of the BCDR (Burst mode Clock and Data Recovery, burst mode clock data recovery) on the next signal subsequent channel is long. In the embodiment of the application, the front reset mechanism and the rear reset mechanism can be adopted simultaneously when the effective optical signals are sent, so that the problem of misjudgment can be solved, and the problem of overlong locking time of the BCDR module can be solved, so that a better comprehensive effect is achieved.
S2: and determining a rear reset starting time corresponding to the effective optical signal according to the first ending time and preset reset configuration information.
The initial time of post-reset corresponding to the effective optical signal refers to the time when the OLT optical module needs to be post-reset after the effective optical signal ends, and in order to ensure the integrity and the validity of the effective optical signal, the time is not earlier than the first ending time, so as to avoid that the effective optical signal is reset. The preset reset configuration information mainly comprises relevant information of whether delay reset is needed and how long delay is needed if delay reset, and after the first end time is obtained, the post reset starting time is calculated according to the specific content of the preset reset configuration information.
In one embodiment, S2 specifically includes:
s21: and when the preset reset configuration information is that delay reset is not needed, determining the first ending time as the post reset starting time.
S22: when the preset reset configuration information is that delay reset is needed, the preset delay trigger time of the OLT optical module is obtained, and the post-reset starting time is obtained according to the sum of the first ending time and the preset delay trigger time.
When the delayed reset is not needed, the first ending time StopTime-T1 can be directly determined as the post reset starting time, and the preset reset configuration information can be configured without delayed reset or the information is directly not configured, so that the delayed reset is not defaulted. If the delay reset is needed, the preset delay trigger time C1 is needed to be configured, then the configured preset delay trigger time C1 is acquired from the configuration when needed, and the sum StopTime-T1 of the first end time StopTime-T1 and the configured preset delay trigger time C1 is used as the post reset starting time. The former scheme can be used for resetting immediately after the end of the effective optical signal, and the latter scheme can be used for resetting after a period of time delay after the end of the effective optical signal. By presetting reset configuration information, the reset starting time can be flexibly selected according to actual conditions so as to adapt to requirements in different scenes.
S3: and generating a rear reset signal at the rear reset starting moment, and carrying out rear reset on the OLT optical module through the rear reset signal so as to enable the OLT optical module to output a target electric signal in a common-mode voltage state from the rear reset starting moment.
At the initial time of the post-reset, a post-reset signal can be generated in the reset circuit and input into the OLT optical module through a corresponding interface in the OLT optical module, and the post-reset is performed on the OLT optical module to restore the gain coefficient and the bandwidth to default values (because the gain coefficient and the bandwidth have been automatically adjusted according to the intensity of the effective optical signal before). After the post-reset, even if noise and other interference still exist, the target electric signal output by the OLT optical module is in a common mode voltage state instead of an unstable state from the initial time of the post-reset.
The determination of the ending time of the post-reset can be configured in the following two ways.
In one embodiment, after S3, further comprising:
s4: and obtaining a preset delay release time.
S5: and determining the corresponding rear reset ending time of the effective optical signal according to the sum of the rear reset starting time and the preset delay releasing time.
S6: and ending the post-reset of the OLT optical module at the post-reset ending time.
In the first way, a preset delay release time T2 may be preconfigured, which is used to indicate how long a reset is required after the start of a post reset. When the post-reset end time is needed, the preset delay release time T2 is directly obtained from the configuration, and then the sum StopTime-T1+T2 (or StopTime-T1+C1+T2) of the post-reset start time StopTime-T1 (or StopTime-T1+C1+T2) and the preset delay release time T2 is used as the post-reset end time. When the end time of the post-reset is reached, the input of the post-reset signal is stopped so as to end the post-reset of the OLT optical module, and from the moment on, the gain coefficient, the bandwidth and the like of the OLT optical module can be automatically adjusted again according to the intensity of the subsequent optical signal, and corresponding electric signals are output to perform normal operation.
In one embodiment, after S3, further comprising:
s7: and acquiring a second front reset starting moment corresponding to the next effective optical signal.
S8: and determining a rear reset ending time corresponding to the effective optical signal according to the second front reset starting time, wherein the rear reset ending time is not later than the second front reset starting time.
S9: and ending the post-reset of the OLT optical module at the post-reset ending time.
In the second mode, the second previous reset start time corresponding to the next valid optical signal may be used as a reference, and the N-beat (N is an integer) before the second previous reset start time may be ended as the subsequent reset end time. The next valid optical signal is an valid optical signal sent after the current valid optical signal, and the second reset starting time, that is, the starting time when the next valid optical signal is sent to the OLT optical module, is the latest time when the last reset end time coincides with the second previous reset starting time. When the end time of the post-reset is reached, the input of the post-reset signal is stopped so as to end the post-reset of the OLT optical module, and from the moment on, the gain coefficient, the bandwidth and the like of the OLT optical module can be automatically adjusted again according to the intensity of the subsequent optical signal, and corresponding electric signals are output to perform normal operation.
Specifically, as shown in fig. 5, the current valid optical signal is transmitted by ONU2, the next valid optical signal is transmitted by ONU1, and the post-reset end time is N beats before the second pre-reset start time. When N is not 0, a time period which is not in a reset state exists between the rear reset end time and the second front reset start time, and when N is 0, the rear reset end time is overlapped with the second front reset start time, namely, the two reset time periods are continuous, so that a longer reset time period is formed.
For some OLT optical modules, after the end of the post-reset, the output of the OLT optical module still can keep a stable common-mode voltage state, and the post-reset time is not required to be too long and can be 10-20 nanoseconds. If some types of OLT optical modules cannot maintain a stable common mode voltage state after the end of the post-reset, the reset cannot be released and the post-reset needs to be continued until the next previous reset is connected. Those skilled in the art can flexibly set the end time of the post-reset according to the needs so as to adapt to the requirements of different scenes.
In the above embodiment, when the post-reset and the pre-reset are simultaneously employed, the pre-reset signal and the post-reset signal may be generated by the same reset circuit and input through the same interface of the OLT optical module, and the two signals may be equal. That is, the structure of the OLT optical module does not need to be changed, only the time sequence of the reset signal needs to be changed to increase a post reset signal on the basis of the existing pre reset signal, and the technical problem that the locking time of the current BCDR module is long is solved with lower cost.
In one embodiment, after S3, further comprising:
s10: the target electrical signal is input to the BCDR module.
After the target electric signal in the common mode voltage state is obtained, the target electric signal is input into the BCDR module as an input signal. The common-mode voltage state enables the subsequent BCDR modules to be in steady-state input from the initial time of the subsequent reset, so that the subsequent BCDR modules can quickly lock signals after the next signal, and correct data can be recovered within a specified time.
According to the above embodiment, in the method for resetting the OLT optical module provided by the present application, the first end time when the target ONU sends the effective optical signal to the OLT optical module is obtained first, then the post-reset start time corresponding to the effective optical signal is determined according to the first end time and the preset reset configuration information, finally the post-reset signal is generated at the post-reset start time, and the post-reset is performed on the OLT optical module through the post-reset signal, so that the OLT optical module outputs the target electrical signal in the common-mode voltage state from the post-reset start time. According to the method and the device, the post-reset mechanism is arranged, so that the output of the OLT optical module is in a common mode voltage state rather than an unstable state after the post-reset initial moment, the subsequent BCDR module is in steady-state input, and the subsequent BCDR module can quickly lock signals after the next signal, so that correct data can be ensured to be recovered within a specified time. That is, the present application alleviates the technical problem of longer locking time of the current BCDR module.
